FAQ

Solar PV stands for Solar Photovoltaic. When some materials are exposed to sunlight, they release small amounts of electricity. This is known as the photovoltaic effect. When describing solar cells, the photovoltaic effect is the conversion of sun energy into electricity by the cells.

The energy that the panels generate is used to power your home during sunlight hours to help reduce the daytime, grid-based, energy usage of your home.

The cost of the systems range from between $5,240, to $13,990 depending on the size of the system. This cost is for a fully installed system, though there may be some additional costs specific to your house, if this is the case you will be advised of these costs following a site assessment.  Each system will also require a new meter to be installed by your retailer.  We will assist to arrange this, but the costs will be charged to you by your retailer.

Genesis Energy has worked with  ANZ, ASB, BNZ, Kiwibank and Westpac to enable their customers with existing home loan lending to apply to those banks for solar finance at home loan rates. If you are interested in this, further information is available here.

Whilst there are costs to you in purchasing and owning the solar system, solar power will help you to reduce your monthly electricity spend by offsetting the energy usage in your house.  How much your monthly electricity bill will reduce by will depend on a number of factors, including the size of the system that you install, how much electricity your system generates, how much electricity you use during the day, what you currently pay for your electricity and changes to the price of electricity over the life of your system.

The key benefit of the Genesis Energy solar package is to offset your energy usage in your home.  If you do produce excess energy then that is sent to the grid and (depending on your energy retailer) you may be given a credit on your electricity bill or paid directly for that excess energy. Please note that New Zealand energy retailers are not obligated to purchase electricity from private solar power systems, and your retailer’s terms and conditions could therefore change at any time. Please check with your retailer to see what they currently offer.  Genesis Energy currently offers around 6c/kWh through our HomeGen programme – separate terms and conditions apply to HomeGen and these are available at Genesis Energy.

No, you don’t even have to be a Genesis Energy customer. However, Genesis Energy electricity customers get $500 off the full price of their solar package.  If you are interested in switching your electricity to Genesis Energy, check out our current offers.

We will send a specialist assessor to assess whether the structural and electrical components of your home are suitable for the installation of the System. The assessment may require our assessor to climb onto your roof and into your ceiling cavity (roof space), as well as assess the electrical wiring of the house. You need to be present at the house during the visit. In preparation for the visit, please ensure that any dogs are restrained and that the roof space is easily accessible.

Typically it takes just one day to install and get your panels up on the roof, although it can take longer if access to your roof and roof space is difficult or there is bad weather.

Once the installation is complete, an independent electrical inspector will visit your property and ensure your system has been correctly installed. Genesis Energy will arrange this inspection and try to make it the day of installation, but it may be up to two weeks later. Once the inspection is complete, the inspector will then switch on the system.  You will also need to be on site during this inspection.

You will also require a new meter to be installed so that the import and export of electricity can be measured at your property.  This will be arranged through your electricity retailer.  Genesis Energy will help you to arrange this with your retailer (even if it is not Genesis Energy) although you will be charged for the meter directly by your retailer.  Genesis Energy currently charges around $100.  If you are with a different retailer you should check with them to see what they charge for a meter changeover.

Your system will be producing solar power once the inspector has turned the system on.  If your metering has not been completed by this stage your solar system will still produce energy that you can use in your home, but any excess electricity that you export to the grid will not be measured so you will not receive a credit for this excess power.

Yes, you will need to install a new meter which will be capable of measuring grid electricity imported and exported at your home.  This will be arranged through your electricity retailer.  Genesis Energy will help you to arrange this with your retailer (even if it is not Genesis Energy) although you will be charged for the meter directly by your retailer.  Genesis Energy currently charges around $100.  If you are with a different retailer you should check with them to see what they charge for a meter changeover

Yes, during the installation we will need to turn off the power while we wire into your distribution board.  When your meter is changed your power will also be disconnected for up to 1 hour.

All of the Solar PV panels are designed to be mounted on top of an existing or new roof and are not normally heavy enough to cause structural problems. However, bolts are used to secure the system to your roof and if the panels are removed, these bolts will remain.

The size of the system is often determined by the available roof space of the property and size of the system you require. As a guide each panel is approximately 992mm wide by 1640mm high in size. Approximately 8 m2 of roof space is required per 1 kW of solar panels.

Solar PV systems do not need generally require planning permission unless the property is a listed historic building or in a conservation area. Genesis Energy does not install on heritage listed buildings.  You will be responsible for obtaining any consents required for the installation of the System.  If your home is on a cross-leased property, you may need consents from other property owners on the cross-lease and we recommend you discuss this with your cross-lease neighbours.

The Genesis Energy Solar Promotion offers Genesis Energy and non-Genesis Energy customers, within 50kms of Auckland, city centre, and the Hamilton and Whangarei areas, a range of solar power systems for purchase (including all equipment (other than metering) and installation).

We are using ReneSola panels with Fronius inverters for string designs, or Enphase inverters for micro-inverter designs.

A string inverter is where an array of solar panels is connected together with a single inverter. It is thought that this type of set up is suited to spaces without any shading, as shading on panel will reduce the entire systems performance.

Micro-inverters partially address shading performance issues as these systems have a small inverter installed on each panel. This solution can cost more at the set up stages, but may provide an overall better performance in certain conditions.

Different components of the system will come with different warranty lengths.  The solar panels have a manufacturer’s 25 year linear power output warranty and a 10 year material and workmanship warranty. The Fronius and Enphase inverters both have a 10 year limited manufacturer’s warranty.

Yes, both the Fronius and Enphase inverters come with monitoring capability.

Once your system is installed you will be provided details on your systems warranty and who to contact should there be any faults.  Further details can also be found in our Solar System Installation Terms and Conditions.

Solar photovoltaic panels require little maintenance.  Your panels can build up dust and other material over time. Solar panel cleaning is not that different from cleaning your windshield. This can be done with soapy water and a soft brush. You should check the maintenance instructions contained in the manufacturer warranties provided with your system to ensure you are maintaining the panels correctly.

No, the solar panels require you to be connected to the local grid for them to operate. If power is cut to your home, the solar panels will not operate.  This is a safety mechanism to protect appliances at your property and for the safety of network maintenance personnel.

Unfortunately there is no battery storage for excess solar electricity available as part of this promotion. However Genesis Energy may be able to offer this in the future.

Cloud and rain are unlikely to stop your solar system from working altogether,  although they will reduce the current output.

Though solar energy is widely available in New Zealand, there are many factors that could affect a houses suitability including roof direction, tree coverage, available roof space and electrical wiring.  You can visit here to see if your house might be suitable for the Genesis Energy solar promotion.

Solar panels that face north get the maximum amount of sunlight during daylight hours to generate electricity. Placing panels on an east or west-facing roof will still produce a substantial amount of power. It is not recommended that you install panels with a southerly aspect, so Genesis Energy will not be installing on south facing roofs during this promotion.
